On the Stability of Rubble Mound Structures under Oblique Wave Attack

Slope stability formulae for rubble mound structures are usually developed head-on conditions. Often, the effects of oblique waves neglected, mainly because it is assumed that wave attack, reduction in damage compared to perpendicular attack insignificant. When incident oblique, required armour size can be reduced case. Therefore, important consider obliquity influence on slope as a factor. One most recent estimating rock-armoured slopes, referred Etemad-Shahidi et al. (2020), was proposed attack. The aim this study develop suitable factor above-mentioned formula. To achieve this, first, laboratory experiment datasets from existing reliable studies were selected and analysed. Then, previously suggested factors evaluated mentioned formula suggested. includes effect directional spreading explicitly. It shown prediction improved by using
